the drawcord is 3/32" nylon
the fabric is a DWR nylon ripstop, unknown weight. and there is no right or wrong side
and actually, it is closing easier now, maybe the fabric was too stiff initially. if it continues to get easier (and since silnylon, which i will be using on the final project, will probably close smoother anyway) i dont think this will be a problem at all.
bill's AT1 pack roll closure looks nice, i wonder how well it works when the collar needs to be expanded though. the shockcord system seems to be designed to work only when filled to standard capasity, not carrying anything in the collar (although i could be, and probably am wrong).
thanks for the help, i will hopefully post pictures soon.
